Logarithmic scales are used. The amplitude response is given in decibels, so it is possible to construct complex Bode plots by superposition of simple subplots. If there are several partial transfer ...

The Nichols chart is used to determine the peak response (most unstable point) from an open loop transfer function plot, as well as the crossover frequency, phase margin and gain margin.

Hence, the second term in the transfer function is no longer one. The approximation that assumes an infinite open loop gain is no longer valid. Another operational amplifier (op amp) performance key ...
